Aquatic Animal Pathology


Research Interests

  • Microscopic and molecular diagnosis of aquatic animal diseases
  • Pathobiology of infectious diseases of aquatic animals
  • Diseases of finfish aquaculture and their prevention

Dr. Camus is interested in the pathobiology of infectious diseases of fish, including the characterization of novel viruses, bacterial species and myxozoan parasites in teleost and elasmobranch species. Previous and ongoing original and collaborative work has involved the characterization of multiple novel fish viruses, including the first complete viral genomes from an elasmobranch species, as well as the pathogenesis of Mycobacterium chelonae infections and the associated immune transcriptome of syngnathid fish, papillomatosis in bluegill sunfish, Branchellion torpedenis parasitism of elasmobranchs, vaccine development and pathogenesis of Fransicella noatunensis orientalis infections in cultured tilapia, pathogenesis of a spaC-type Erysipelothrix sp. infection in ornamental fish, Veronaea botryosa infections in white sturgeon, epitheliocystis disease in elasmobranchs, and gill epithelial hypertrophy in soft clams.

Educational Background

  • DVM (1984) Louisiana State University
  • Residency (1994) Louisiana State University
  • PhD (2001) Louisiana State University


Dr. Camus is focused primarily on diagnostic service in fish diseases and a resident training program in aquatic animal pathology in partnership with the Georgia Aquarium, Atlanta, GA. He has served previously as a pathologist for the Louisiana Aquatic Animal Disease Diagnostic Laboratory and as Director of the Aquatic Diagnostic Laboratory, Thad Cochran National Warmwater Aquaculture Center in Stoneville, MS, working closely with aquaculture interests in the southeast. Dr. Camus is a member of the Fish Health Section of the American Fisheries Society and the World Aquatic Veterinary Medical Association (WAVMA).
